Description
It has been recently pointed out that gluons can be linearly polarized even inside an unpolarized hadron provided that gluons should have non-zero transverse momentum with respect to the parent hadron. The effect of linearly polarized gluons on transverse momentum (PT ) and rapidity (y) distributions of J/ψ and Υ production is studied within the framework of transverse momentum dependent (TMD) factorization employing color evaporation model (CEM) in unpolarized proton proton collision. The estimated PT and y distributions of J/ψ and Υ have been modulated by the presence of linearly polarized gluons inside unpolarized proton at LHCb, RHIC and AFTER energies. Therefore, quarkonium production is a handy process to extract the unknown density function of linearly polarized gluons.
